"DIAGNOSIS: Medium-sized scorpion
with long, thin cauda and heavy, elongated pedipalps, with basic
characters of mordax except as follows: mature females about 45 mm. in
length; median eye tubercle situated well in front of middle of
carapace; pectinal tooth count of female 12, of male 14; lower margin of
movable finger of chelicera essentially smooth; palm of chela large,
twice as long as wide; inferior lateral and median keels of basal
segments of cauda granulated, with crenulated margins.
COLORATION: Base color
of mature specimens dusky reddish
brown; legs, sternites of preabdomen, chelicerae, and telson yellowish.
STRUCTURE: Similar to that of mordax and in both sexes unless otherwise
indicated. For measurements, see table 3.
Carapace: Carapace thickly covered with quite coarse granules over most
of surface, those of interocular triangle smaller and heavy row on each
side margining this area; frontal margin with six short spines. Frontal
emargination deep and rounded. Ocular tubercle of average size, placed
well in front of middle, the eyes at this point about one-third distance
between front and posterior margin. Median eyes small, 0.3 mm.;
separated by nearly their diameter. Lateral eyes (figs. 17, 18) two or
three; third eye obsolete in some adult specimens, still present in
Preabdomen: All tergites finely to coarsely granulated, mostly on caudal
half; tergite VII with prominent, long keels, of which middle pair is
finely granulated and side pair provided with about 30 coarse granules;
intercarinal spaces of tergite VII with numerous small and large
Cauda: All caudal segments longer than broad; caudal segment V as long
as carapace. All keels prominent, distinctly but finely granulated to
give crenulate to serrate appearance in lateral view; single inferior
median keel of segment V weakly bifid in holotype, not so in other
mature female; intercarinal spaces of segment V with little granulation.
Telson: See figures 122, 123. Vesicle about as wide as caudal segment V,
elongate oval, less than half as deep as long, smooth above, lightly
granulated below and on sides; sting moderately curved, less than half
as long as vesicle.
Pectines: Like those of mordax but with more elements. Middle lamellae,
eight in female, 10 in male; pectinal teeth, 12 in females, 14 in males;
outer pectinal tooth larger than others; median piece with shallow,
Chelicerae: Keel on lower margin of movable finger smooth.
Pedipalps: All keels of femur and tibia granulated. Frontal spurs on
tibia small, single, rounded projections bearing stout spine. Chela
stout, elongated, with palm almost twice as long as broad; movable
finger shorter than palm; position of keels like those of mordax;
superior keel with numerous granules, distinctly crenulate; all other
keels finely granulated and intercarinal spaces with few granules.
pattern as shown in
Walking legs: With basic spination of mordax but spinules minute and
spines of small size; single row of spinules on venter of tarsus with
irregular row of few fine spines on each side."
